Android LowClickInEnabled（true）将导致首选项真正被禁用，但当您单击它时，它将调用回调

在我们的例子中，我们想让复选框保持禁用状态，同时启用标题和摘要文本视图，但您可以根据自己的需求随心所欲。更新了代码。

“是否可以禁用首选项，但仍能处理对其的单击？”--可能不会。我的猜测是，它们将底层小部件标记为已禁用，并且您无法接收已禁用小部件的单击事件（因为它们已禁用）。就我个人而言，我会对依赖权限的首选项使用单独的首选项屏幕，您可以控制用户如何进入这些屏幕的UI。@Commonware事实上，在问了这个问题后，我很快就找到了一个解决方法，但我仍然希望它能很好地工作。请检查我下面的答案。
